' CULTIVATOR.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed October 5, 1905. Serial No. 281,504-

To all whom it may concern:

Be it known that I, EUGENE ROSENBAUM, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivating implements; and the objects of the invention are to promote simplicity and efliciency in the construction and operation of this class of devices.

With these and other ends in View, which will readily appear as the nature of the invention is better understood, the same may be described as consisting, essentially, in the combination, with a cultivator-beam, of sets of parallel bars pivotally connected therewith, said parallel bars being connected in pairs byteeth which constitute the earth-engaging implements, and a circular brace permanently connected with the beam and adapted for connection with the parallel bars in any position to which said parallel bars may be adjusted for the purpose of retaining them in operative position.

The invention further consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be resorted to when desired.

In thedrawings, Figures 1 and 2 are top plan views of a cultivating implement embodying the invention and showing the parallel bars in different positions. Figs. 3 and 4 are top plan views showing the parallel bars in still other positions and illustrating a slight modification in the construction of the circular brace. Fig. 5 is a sectional detail view taken on the plane indicated by the line 5 5 in Fig. 4.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

In the several figures of the drawings, 1 designates an ordinary beam provided at its rear end with handles 2, whereby it may be guided. Extending vertically through the beam are pivotal members 3 a, upon which are pivotally mounted pairs of laterally-extending bars 3 3 and 4: 4c. The bars 3 a are retained in parallel relation to each other by means of the cultivator-teeth 0r earth-engaging implements 5, which are pivotally connected with both of said bars. The bars 3' 4 are in like manner retained in parallel relation by means of the cultivator-teeth or earth-engaging implements 5', which are in like manner pivotally connected with both of said bars. An additional cultivator-tooth may be secured upon the bolts or pivotal members 3 4, as shown at 6 in Fig. 5 of the drawings.

By the relative arrangement of the beam and the pivoted tooth-carrying parallel bars, which has been just described,- the said parallel bars may be disposed for operation in any of the various positions illustrated in the several figures of the drawings or, in fact, in many intermediate positions to which the parallel bars may be moved by swinging them upon their pivots. For the purpose of securing the tooth-carrying bars at any of their various adjustments there is provided a circular brace 7, which is firmly and permanently connected to the beam 1, as by means of bolts 8. Under the construction shown in Figs. 1 and 2 this brace may be an integral metallic ring or band. Under the construction shown in Figs. 3, 4c, and 5 the ring or band may be composed of two separate overlapping sections, individually designated 9, but combined to form a complete circle. This circular brace is provided at intervals with apertures 10 for the passage of connecting-bolts 11, which also serve to connect the teeth pivotally with one of the parallel bars at each side of the beam, said bolts being provided with wing-nuts 12, so that any desired adjustment may be easily and quickly effected.

The circular brace of the device has been described as being permanently connected with the beam. Thereby is meant that said brace is permanently stationary and that the position of said brace is not afl'ected by any change of position or adjustment of the pairs of parallel bars carrying the earth-engaging implements.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains.

A cultivating implement constructed on the lines herein described may be adapted to adiversity of uses, and in any of the diverse positions occupied by the parallel tooth-carrying bars the latter will be firmly secured against displacement by means of the bolts whereby they are connected with the circular brace, and the latter has the additional advantage of preventing displacement in an upward direction of the free ends of the toothcarrying bars. v

The general construction is simple and inexpensive, and the device has proven efiicient in operation.

Having thus described the invention, what is claimed is 1. A'beam, pairs of parallel bars connected pivotally with and extending in opposite directions from the beam, earth-engaging members pivotally connecting the parallel bars and serving to keep them in parallel relation, a circular brace securely connected with the beam, and means for connecting one of each pair of parallel bars adjustably with the circnlar brace.

2. A beam, pairs of parallel bars connected pivotally with and extending in opposite directions from the beam, earth-engaging members connected pivotally with the parallel bars and serving to retain the latter in parallel relation, and means permanently connected with the beam and adapted for temporary engagement with one of each pair of parallel bars to maintain the latter in any of the positions to which they may be adjusted.

3. A beam, pairs of parallel bars connected pivotally with and extending in opposite directions from the beams, earth-engaging members connected pivotally with the parallel bars EUGENE ROSENBAUM.
